The Kock pouch is a continent ileostomy in which a reservoir of ileum can be accessed via a small, one-way valve stoma also created from ileum. The stoma is not spouted, but instead a smaller opening is created to allow a intermittent intubation to allow flow of faeces (and influx of wash or enema).
It is often misspelled as 'Koch pouch', possibly to avoid confusion with a urological procedure.
It has been replaced by restorative proctocolectomy involving J-, W- and S- pouches.
